Fault code description故障码说明

DTC故障码(DTC)	Fault code description故障码描述	Possible cause of failure可能故障原因
P16E298	The battery temperature is seriously too high电池温度严重过高	1. The battery temperature exceeds the allowable range and the cooling system does not work properly.1.电池温度超出允许使用值范围，冷却系统未正常工作

Troubleshooting steps故障诊断步骤

①Check coolant检查冷却液

1. Check whether there is enough coolant.检查冷却液是否充足。 Are the test results normal?检查结果是否正常？ Yes是 Go to step 2.去步骤2。 No否 After repairing or replacing faulty parts, add coolant that meets the specifications.维修或更换故障部件后添加符合规格要求的冷却液。

②Check ambient temperature检查环境温度

1. Check whether the vehicle operating environment temperature is too high.检查车辆运行环境温度是否过高。 2. After leaving the vehicle alone for a period of time, check whether the fault code and symptoms are eliminated.将车辆静置一段时间后，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Go to step 3.去步骤3。

③Check the thermal management integrated module fault code检查热管理集成模块故障码

1. Use a diagnostic tool to read the fault code of the thermal management integrated module and check whether there is a fault in the integrated temperature control system.使用诊断仪读取热管理集成模块故障码，检查集成温控系统是否存在故障。 Are the test results normal?检查结果是否正常？ Yes是 Go to step 4.去步骤4。 No否 Repair the integrated temperature control system.检修集成温控系统。

④Replace the battery pack assembly更换电池组箱总成

1. Replace the battery pack assembly with a new one and check whether the fault code and symptoms are eliminated.更换新的电池组箱总成，检查故障码及症状是否排除。 Are the test results normal?检查结果是否正常？ Yes是 Fault resolved.故障排除。 No否 Look for causes from other symptoms.从其他症状查找原因。   Caution:注意： ♦  After replacing the battery pack assembly, you need to use a diagnostic tool to recalibrate the battery pack assembly.更换电池组箱总成后，需用诊断仪对电池组箱总成重新标定。
